Global Dynamics and Imbalance Effects in the Lucas-Uzawa Model: Further Results

2007

In this paper we use a new analytical approach to the Lucas-Uzawa model (Boucekkine and Ruiz Tamarit, 2007) to extend the existing results on the dynamics, and notably on the imbalance effects arising in the model. The approach does not only allow to extend the traditional analysis to any initial conditions and for all variables in level, but it also permits a more general investigation of imbalance effects.

On international spillovers

2012

Abstract This study investigates the role of international spillovers in generating productivity gains for a panel of 24 OECD countries during the period between 1971 and 2004. We use recent techniques developed in a common factor framework to characterize the global interdependence implied by international spillovers and the diffusion mechanisms involved. Consistently with some recent studies in this field, the evidence suggests that there are substantial cross-country spillovers mainly related to R&D and human capital variables, which contribute significantly to productivity.

Global Divergence in Growth Regressions

2013

This paper extends the standard growth regression model by adding an assumption that a country follows the global technology frontier either fully or partially. This additional assumption changes significantly the growth regression model and its results in three main ways. First, it shows that although a country converges to its long-run growth path, this path can diverge from the countries at the global frontier. We measure the degree of divergence for each country and find that most indeed diverge from the frontier. Second, we estimate growth dynamics without controlling for additional variables. Third, our new method enables us to disentangle the effects of the explanatory variables on t…

NATIONAL COMPETITIVENESS - SCENARIOS FOR ROMANIA

2012

Competitiveness remains a continuous concern of nations in any stage of development, from factor based economy to innovation based economy. The present paper aims to emphasize the current level of national competitiveness of Romania, on one hand, and to identify possible ways to improve the current level by building scenarios in order to eliminate the uncertainty, on the other hand. The paper proposes four scenarios for increase GCI (growth competitiveness index) and four scenarios from pessimistic point of view (in these scenarios GCI will be decrease). In the near future, Romania must improve their pillars of national competitiveness and must increase their GDP per capita for transition p…
